This component is a 2.5mm (3.5mm is more common) headphone connector socket, designed for permanent and robust PCB integration via its through-hole, right-angle mounting pins. This orientation allows the cable to exit parallel to the circuit board, saving vertical space in compact designs. It features a TRS (Tip-Ring-Sleeve) configuration with three poles, supporting standard stereo audio signals (left and right channels plus a common ground) without an integrated switch function. Notably, it is rated for a higher power capacity of DC 12V at 1A, indicating its suitability for applications beyond simple audio, such as in low-power device charging or data transmission where this connector format is specified. The presence of four conductors, despite being a 3-pole TRS jack, typically includes an extra solder lug for enhanced mechanical stability and grounding. Constructed for durability, it ensures reliable signal integrity and connection longevity in consumer electronics, communication devices, or specialized industrial equipment.
